Title: Circuit Arrangement For A Multi-Stage, Regular Crosspoint Arrangement
IPC: H04Q3/00
Filed: 1968-01-18
Abstract: 1,153,964. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 18 Jan., 1968 [25 Jan., 1967], No. 2692/68. Heading H4K. In a multistage switching network in which each matrix of one stage is connected via one link only to a matrix of an adjacent stage and each matrix has an associated marking relay which is brought up (when a path has been selected) preparatory to the switching-through of this path, each link includes two control wires, the marking wires of like-numbered rows of the severed matrices in a stage are multipled and each crosspoint relay has a series make contact with a diode connecting the junction of the relay and contact to the associated row marking wire. A crosspoint relay is operated by apply ing potentials to the relevant control and mark ing wires, the values of the potentials used at each stage differing from those in the adjacent stages by an amount equal to the operating potential of a crosspoint relay. Operation.-A preselected path between U2 and U1 via matrix KVB2 in the second stage is set-up by operating matrix marking relays HA1, HB2 and HC1, closing contact k (junctor side) to apply + 12 V to the outlet U1 and closing contact EM to apply - 24 V to the inlet's row marking wire ma1. Contact ha13 extends -12 V over the second control wire eb2 of link ZL2 (and also over eb1 of link ZL1 but this is irrelevant) so that link marking relay BB1 comes up in stage B (contact hb21 is closed because HB2 is up). The - 12 V is extended back over link ZL2's first control wire cb2 via rectified G<SP>1</SP>21 whereby KPA2 operates to switch through the speech wires (not shown) and to close its self-holding contact kpa2. In stage B with BB1 up, - 12 V is applied to row marking wire bb1 so that KPB1 can be energized due to the simultaneously occurring earth on the second wire ecn (and hence also the first control wire ccn) of link ZLn. The earth on ecn additionally brings up CB2 in order to provide earth to the row marking wire mc2 and hence operate KPC3. The above processes occur vertically simultaneously. The crosspoint relays KPA1, KPB1 and KPC3 hold from a potential U2 (more negative than - 24 V) to a potential U1 (more negative than earth), the matrix and row marking relays HA1, HB2, HC1 and BB1, CB2, and the contacts k and EM then being released. It should be noted that the crosspoint relay operating potentials for stages A; B; and C are respectively - 24 and - 12; - 12 and earth; and earth and + 12 V, i.e. the potentials in each stage differ by 12 volts from those in adjacent stages, 12 V being the potential required to operate a crosspoint relay. In an alternative embodiment (Fig. 2, not shown) the diodes, e.g. G21, G<SP>1</SP>21 connected to the inlet end of each link are dispensed with, operating potential for a crosspoint relay in the preceding stage being reverted over the links first control wire by connecting the latter to its associated row marking wire via a contact of the matrix marking relay.

Title: Improvements in or relating to method of and apparatus for making soap
IPC: C11D13/04
Filed: 1938-05-27
Abstract: 519,565. Soap; glycerine. REFINING, Inc. May 27, 1938, No. 2704/40. Convention date, May 28, 1937. Divided out of 519,516. [Class 91] ' Soap and glycerine are obtained continuously by mixing in stream flow alkali and fat or like, effecting substantially complete saponification while maintaining a temperature below that at which discoloration due to unsaponified fat or the like will result, heating the mixture in an independent zone to a temperature substantially above the melting point of the soap when anhydrous and passing it so heated into a preferably evacuated vapour-separating zone. For example, proportioned quantities of fat and alkali are drawn by pumps 7, 8 from containers 5, 6 through preheaters 11, 12 to a mixer 18, and passed by a pump 20 through a heated coil 24 ; the soap produced is forced through a pipe 28 and a mixer or pump 30 where any untreated fat is saponified, and then through a pipe 29 and a heated coil 69 to a pipe 75 and discharged, e.g., from a nozzle 81 into an evacuated chamber 80 ; the molten or plastic soap is withdrawn by air-tight conveyers 103, 106 provided with cooling jackets 109, 110 ; the vapours flow in a pipe 87 to glycerine and water condensers 91, 96 connected to a vacuum pump 100. The mixer 30 may be a rotary or reciprocating pump, or a jacketed screw-conveyer preferably fitted with a perforated transverse plate ; it may be replaced or assisted by increasing the turbulence in the soap stream, e.g., by flowing the soap from the coil 24 to the pipe 28 through the thermostatic control 27 so as suddenly to reverse its direction. The fat is usually preheated, as by the coil 11, to 200-350F., but it may be 100-400F.; the alkali is usually preheated to 100-220F. Suitable temperatures in the coil 24 are 350-425F. with pressures of 50-250 lbs. at a gauge 63. In the coil 69 temperatures of 455-600F. are suitable. The soap may be further heated in the chamber 80 by the jacket 83 or/and by injecting steam or gas. A vacuum of 27-28 in. in the chamber 80 is satisfactory when all glycerine is to be removed. Water, perfumes, fillers, and other materials may be added to the soap in the conveyer 106 or later. Specifications 471,172, 487,470, and 519,516, are referred to.

Title: Improvements in or relating to the preparation of 1-alkynes
Inventor: PINCHIN FRANK JAMES
IPC: C07C1/30
Filed: 1955-01-31
Abstract: In a modification of the process for preparing a l-alkyne claimed in the parent Specification the alkyne is separated from the vapours released from the solution with simultaneous or subsequent condensation of the residual vapours and the condensate so formed, optionally after removal of water, is fed into a second separate heated solution of an alkali metal hydroxide or alkoxide of an alcohol boiling above 100 DEG  C. in an alcohol boiling above 100 DEG C. and separating the alkyne from the vapours released from the second solution, which solution is at least 50 per cent saturated with an alkali metal alkoxide or hydroxide.  In an example, ethoxyethoxyethanol and caustic soda were charged into a mild steel vessel and heated to 160-170 DEG  C. and dichloropropane passed in. The gases evolved were cooled by a condenser at -5 DEG  C., giving uncondensed gas which is chiefly propyne, and two liquid phases, the upper one of which was returned to the reactor. The chloropropylene phase of the liquid condensate was then fed to a second vessel and stirred at 160-170 DEG  C.  The gases evolved from the second reactor were combined with those from the first reactor prior to being fed to the condenser.  Specification 777,141 also is referred to.

Filed: 1955-02-01
Abstract: 764,267. Colour television. GENERAL ELECTRIC CO. Feb. 1, 1955 [Feb. 1, 1954], No. 2994/55. Class 40 (3). [Also in Group XL (c)] The synchronizing burst carried on the back porch in a colour subcarrier television system is separated from the signals in the chrominance channel 2 by applying the signals through a cathode-follower stage 10 to a normally non-conducting stage 38 which is gated on during the burst interval by positive pulses 39 from a source 40. The synchronous detectors are fed via potentiometer 26 from the tuned circuit 16 forming the load of the cathode follower, and the circuit is arranged so that the low impedance presented across the tuned circuit by the input of stage 38 when the stage is gated on reduces the amplitude of the burst signal fed to the synchronous detectors. This prevents the D.C. restorers associated with the synchronous detectors from establishing a false level. A series resonant circuit 32, 34 tuned to the sub-carrier frequency is included in the lead from the cathode-follower to prevent the low output impedance from short-circuiting source 40. When the system is arranged to operate at intermediate frequency, circuits 16; 32, 34; and 56 are tuned to the intermediate frequency of the sub-carrier.
